madisonfinley wroteA guitar is notated one octave above the notes it sounds.

I think this is a mater of semantics and visualization. You are correct, of course . . .

Middle C is portrayed as being the note at the 3rd fret of the low-pitch "A" string, but in fact is lower than actual Middle C, which is the note at the1st fret of the high-pitch "b" string . . .

I think we are saying the same thing but in different ways . . .

I suppose that pretending Middle C this way is the same as saying it's shown an octave higher than it actually is . . .

Regardless, it confused me for decades; but after discovering Scientific Pitch Notation and a few more things, I realized that Middle C on an electric guitar is the note at the 1st fret of the high-pitch "b" string rather than the note at the 3rd string of the low-pitch "A" string . . .

Even today, when I see Middle C in music notation, I visualize the 3rd fret of the low-pitch "A" string of an electric guitar, which is wrong . . .

It's all the worse when I look at a bass clef staff, because to determine the correct note requires me to stop and to remember if it's two whole notes lower or higher than on a treble clef staff . . .

After a few seconds, I remember that C looks like A when on a bass clef staff . . .

This is the reason that for me trying to sight-read bass clef staves is simply impossible . . .

My brain is hard-wired to make intuitive sense only of soprano treble clef staves . . .

For reference, I use this set of names for the strings on an electric bass {E, A, D, G}; and I use them as names of the four lowest pitch strings on an electric guitar, even though they are an octave higher on electric guitar {E, A, D, G, b, e} . . .

[NOTE: For me, this is intuitive since I started playing bass years before I taught myself how to play guitar . . . ]

I do everything this way now--using soprano treble staves for nearly all instruments . . .

For electric bass, I set its Transposition in NOTION Score Setup to play notated C two octaves lower, but for electric guitar I set it to play only one octave lower . . .

This way, it's all soprano treble clef, which I can read on the staff; several notes below the staff; and several notes above the staff . . .

For me it's easier to remember, since the notes are the same (12 notes in total) but differ by octave (10 octaves), which I suggest is mathematically elegant . . .

madisonfinley wroteThe definition of Middle C seems to depend on what we were taught, and the vendor who created the hardware or software.

I use a lot of IK Multimedia music software, and IK Multimedia is an Italian company . . .

They consider C3 to be "Middle C", which I suppose is an European thing . . .

Here in the sound isolation studio, Middle C is C4 . . .

madisonfinley wroteThe reason for some horns to be transposing instruments? Think of different size saxophones. Should a sax player learn a different fingering for each sax? No. They know that if they finger F, it is an F on that horn, and the resulting pitch will be determined by which key the horn was built in. Otherwise, no sax player could keep the fingering straight switching between saxes of different keys.

This is consistent with my perspective regarding 12 notes and 10 or so octaves . . .

Saxophone players tend to know a lot of music theory and all that stuff, hence are what I consider to be smart folks; and at some point I think most or all of them had the epiphany that it's just a matter of octaves, which is the way I view it for everything . . .

I map everything to soprano treble staves; so here in the sound isolation studio, music notation for electric bass is the same as music notation for every other instrument . . .

If I want a note to be deep bass, then I play or compose it that way; and the same is true for everything else . . .

The notes--and in this comparison, the finger positions--are the same; so it's only a matter of octaves . . .

madisonfinley wroteIs it possible that you have the wrong option in the View menu, where all instruments are shown in concert pitch?

Some of the visual representations of notes will vary depending on which of the three viewing options one prefers; but this is not the cause of the problem you have encountered . . .

At first, I thought it might be just a matter of the viewing option; but after doing some experiments I determined that the problem is NOTION not doing the Transposition as specified in NOTION Score Setup . . .

How you view it (Transposed, Concert Tuning, Concert Pitch) does not affect the problem . . .

I consider it to be a programming error, because it does not do what it says it does . . .

For example, it does not play notated C as B♭ . . .

Basically, it ignores the "odd" intervals; but it correctly handles the octave intervals (one or two octaves, higher or lower) . . .

NOTION 4 ~ NOTION 5 ~ NOTION 6

I clone my hard drives regularly and over time this maps to having older versions of software available . . . .

In this instance, I have NOTION 4, NOTION 5, and NOTION 6; so I did some experiments, and the "odd" types of Transposition do not work in any of these version fo NOTION . . .

Yet, the "octave" types of Transposition work . . .

From this I suggest that the "odd" types never worked . . .

For reference, this is the case with the native NOTION instruments and VSTI virtual instruments and their respective sampled-sound libraries . . .

ANOTHER POSSIBILITY ~ SEND NOTES FROM NOTION TO STUDIO ONE PROFESSIONAL

There is another possibility I am exploring based on a bit of advice from NOTION Technical Support, which is to send the notes from NOTION to Studio One Professional rather than to do it in a ReWire session . . .

I did the experiment, and it does not key on the information specified in the Transposition section of NOTION Score Setup . . .

Lots of FUN!
